A few more technical details emerged of the Perrinn myP1 car, still set to tackle the 2015 Le Mans 24 Hours.

From the official Perrinn myTeam newsletter:

Driver seats on the left as, with more corner to the right at Le Mans, it gives him a better visibility to the apex point.


A 1 piece monocoque would be best but suppliers require access during layup phase which is why it is made in 2 pieces - I have decided for a split at floor level rather than in the middle because it creates a stronger bonded assembly. It is also what F1 people do. Yes the keel shape is integrated to the monocoque to save weight and improve local stiffness - I have tried many different keel shape to make sure the one we have won't need any further short term developments.

Zylon panel (also called side intrusion panel) is build as a separate piece and bonded later - this way it is easier to control thicknesses of each component rather than having variable thickness in the zylon panel zone if you combine the parts.

Same for the internal reinforcement - I prefer to build them as seperate pieces that are then bonded to avoid variable thicknesses - just makes each part more consistent and simple to make. I prefer to not make any exception so that people who build the monocoque have got only 1 layup for the all surface.

All chassis inserts are aluminium

No Rohacell for the chassis reinforcement as again the 'omega' parts are build separately and then bonded.

Yes some areas of the car looks 'underdeveloped' aerodynamically but it is a result of testing various solutions and coming back to a simple shape that still provides the performance - instead of selecting a more complex shape with the same performance that would then be more difficult to build and heavier as a consequence.

Yes we have an option to add frame tubes (carbon) between the top of the chassis and the gearbox/bell-housing to help with rigidity but in the case of the V8 engine, I consider that these are not needed (and space to connect to the bell-housing is not sufficient in that case anyway).

I know the Porsche 919 has got a few add-on aerodynamic bits at the front (we call them penna and barge-boards) - i have tried them and they are only re-balancing the car (moving the aero balance forward) rather than giving a gain in efficiency - and I haven't selected to keep them as we don't need them at the moment. Could change in the future.

Also, the first phase of the model will be unveiled on Wednesday, the 25th.
